Designed with the latest technology in fluid dynamics, HALO eye/face wash covers 85 percent of the user’s face, the manufacturer says. It incorporates an exclusive self-draining feature, which eliminates standing water left in the unit between uses and testing. Self-draining Aquaduct™ design reduces the risk of bacteria growth when the unit is not in use. Bradley Corp.,www.bradleycorp.com/HALO/, (800) BRADLEY.
